Review on 🔧 Bar's Leaks HDC Radiator Stop Leak Tablet – 60g: Top-Notch Solution for Radiator Leaks by Michael Wilson

I have used this product on many GM vehicles over the past 15 years. Will it stop the squirting leak, no. Will it prevent the pinholes from leaking and seeping around the gaskets and o-rings, yes. I use it in every car I own to prevent nasty leaks. I break tablets with a hammer and mix them with coolant instead of just tossing a full tablet into my cooling system. For preventative maintenance, this works. If you're expecting this to be a panacea for a big leak, you'll be disappointed. You need to fix the actual problem.
